We are still taking orders for Sleeper Pipes.....

SP #76 just shipped out for Baldboy's very cool CT175 Rick C is building.

Let us build one for you !

Post up here or send me a PM if you have questions or want to place an order ?

I also have Sleeper pipe 75 here on T-Bone's 1969 CT1 !
If you haven't ordered one yet, you should ! AMAZING performance !!!!

Just wondering .........how would one of your pipes handle a DT1 GYT/MX cylinder? Most likely be running a 32mm carb.
Looking at getting the bike registered in Australia for road use.
While I am at it, I have another odd question along the same line as above. How would it handle a RT1 GYT/MX cylinder?

I can say that a sleeper pipe would definitely handle both the DT1MX and RT1MX cylinder a lot better than the stock pipe would. The porting on both of those cylinders are setup for upper end power. The upper end power hit with a sleeper pipe would be less than the GYT or MX expansion chamber...but you will gain some midrange power with a sleeper.
So the sleeper is a good way to go if your going to be street riding with an MX cylinder.
BTW I have a ported RT2/3 cylinder that will pull to over 9k... that I have tested with a Sleeper Pipe.

Sleeper pipe is first modification on the ct1 Rick C mentioned. Third one on 3 different bikes. Love the um.

Thanks Don and Dave. Great product.

Thanks for the reply above regarding GYT cylinders. Just one more question if I could. Would the sleeper pipe for a standard ported DT or RT be the same pipe for a GYT MX or would you make it with different rpm in mind?
I appreciate your time.

We have played with different cone shapes and placements and we have come up with a standardized cone and placement configuration for each of our sleeper pipe models by actual on road testing. Our Sleepers pipes are designed to typically enhance the midrange power along with the upper end enhancement too.

If your are looking for a more upper end pipe...we can build a custom sleeper to enhance top end power to go along with a GYT or MX cylinder.
If you are considering having us build a sleeper for you...out of country guys buy a suitable pipe on Ebay in the US and have it shipped directly to us and then we ship the finished sleeper to you.

I hope I have answered your questions ?

Would like to build one for you

We are not accepting any more sleeper pipe orders for the next month or so....
Its time for some R & R...!


Thanks again everyone for your continued support
